I apologize...I usually am the one complaining to others about
versioning...my bad...
I do not think that the drive is at fault as much as the controller. I have
had to deploy well over one hundred of the exact same configuration, and
historically, it's always been the controller that just drops the drive for
some reason. I usually end up re-mirroring the array on the old "dead" drive
and the system will continue on its merry way (last one is over 1 year old
since last resync)...hence you see why I am curious if I could just use
atacontrol instead of taking the unit offline and spending 45min waiting for
the resync....

You don't tell us what version you use, but promise is supported very well,
even in atamkII in 6-current.
If you replace the failed drive it sould be automatically rebuilt, the
`atacontrol rebuild ar0` doesn't work as long as you (in 5.x) used
"addspare"
or the controller found a good "spare" drive.
In 4.x you don't have the addspare option, you have to `atacontrol detach 3`
and reattach it the same way to get recognized and inserted as spare in an
existing array.
